Protoverb

Protoverb is an experimental room simulator reverb

Most algorithmic reverberations attempt to avoid resonances or model sound reflections off the walls of a room.

Protoverb does the opposite. It builds in as many room resonances as possible by modeling the air body of the room. There is no need to modulate or color the signal. The result is a very natural sounding reverb with interesting characteristics:

Notes held longer tend to build up resonance, as if the air is slow to excite. Multiple instruments remain distinct, without disappearing in a wash. When a short melody is played, the room seems to repeat a phantom echo of that melody. These properties are found in churches and large halls, but rarely in conventional algorithmic reverberations.

To achieve this, Protoverb works with many parallel, serial and networked delays. With such a structure, no mathematical formula can make it sound good, but rather trial and error (and luck) using random values. Protoverb generates random delay line lengths, networks, and feedback strategies. If you are lucky, you will find a great configuration, which you can send us.
